How the Solana WooCommerce Plugin Works

When a customer selects Solana as their payment method at WooCommerce checkout, SOL Checkout generates a unique Solana Pay payment request with a QR code. The customer scans the QR code with any Solana wallet app (Phantom, Solflare, Backpack) and approves the SOL payment. SOL Checkout automatically verifies the transaction on the Solana blockchain and marks the WooCommerce order as paid — all within seconds.

SOL Checkout WooCommerce Plugin — QR Payment Page

FEATURES

Everything You Need to Accept Solana Payments on WooCommerce

The free Solana payment gateway plugin covers every WooCommerce merchant. Pro unlocks advanced analytics, webhooks, and priority support.

Solana Pay QR Codes

Standard solana: URI QR codes compatible with Phantom, Solflare, Backpack, and all Solana Pay wallets.

Auto Payment Verification

Queries Solana JSON-RPC directly — no API keys, no third-party services required.

Heartbeat Security

HMAC-SHA256 wallet address integrity verification every 5 seconds prevents swap attacks.

Multi-Wallet Load Balancing

Distribute payments across multiple wallets with round-robin balancing.

RPC Fallback Chain

Automatically falls back through mainnet-beta → Ankr → Helius if primary endpoint fails.

Block Checkout + HPOS

Fully compatible with WooCommerce Blocks checkout and High-Performance Order Storage.

SECURITY FIRST

Wallet swap attacks are a real threat. We stop them.

SOL Checkout runs a cryptographic heartbeat every 5 seconds using HMAC-SHA256. If any plugin or script modifies your wallet address on the payment page, the transaction is immediately invalidated and you receive an email alert.

HOW IT WORKS

Set Up Your Solana WooCommerce Payment Gateway in 5 Minutes

Install & Configure

Upload the plugin to WordPress, activate it, and enter your Solana wallet address in WooCommerce → Settings → Payments → SOL Checkout.

Customer Checks Out

At checkout, the customer selects SOL Checkout. They see a Solana Pay QR code and wallet address with the exact SOL amount due.

Payment Confirmed On-Chain

The plugin queries the Solana RPC API every 2 minutes. When the transaction is detected, the order is automatically marked paid.

Funds in Your Wallet

SOL lands directly in your wallet — no intermediary, no withdrawal delay, no platform holding your funds.

Why Solana? Because speed matters at checkout.

Solana finalizes transactions in ~13 seconds (32 slots). Compare that to Bitcoin's 10-minute block time or Ethereum's gas fee unpredictability. For merchants who want fast, low-cost crypto payments, Solana is the clear choice.
